Settings of the failsafe F-DO
The settings are displayed after double-clicking "4 F-DO
DC24V/2A" (see "Overview picture").
DIL switch settings
This value has to be set on the module (F-DO).
F monitoring time
It has to be observed that the F monitoring time must be
larger than the call time of OB 35.
Activate the used channel 0, deactivate channels (1, 2, 3)
which are not used.
The output of channel 0 provides the pick-up/drop-out of the
contactor coils of K1 and K2.
The read-back time defines the duration of the switch-off process
for the respective channel. If the respective channel
switches high capacity loads the read-back time should be set
sufficiently. We recommend to set the read-back time as small
as possible by trying, however large enough to ensure that the
output channel is not passivated.
Settings for the readback signals
The readback signals ("K2_HELP" is shown in the screenshot)
are read in via a standard input module of the ET 200S; they
don't have to be read via a failsafe input module.
